Recombinant protein separation device

The utility model discloses a recombinant protein separation device which comprises a liquid storage box body, one side of the liquid storage box body is in threaded connection with a liquid discharge valve, a reaction kettle is welded and fixed at the top end of the liquid storage box body, a precipitation mechanism is arranged in the liquid storage box body, and the precipitation mechanism is used for precipitating and filtering recombinant protein in separated clear liquid. And the reaction kettle is internally provided with a separation mechanism, and the separation mechanism is used for carrying out ultrasonic stirring on the interior of the salt solution so as to carry out separation treatment on the protein in the stock solution. In the operation process, the ball screw drives the power storage supporting plate base to repeatedly ascend and descend, the power storage supporting plate base provides a power source for the ultrasonic module on the outer side, the ultrasonic module repeatedly conducts ultr
